4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the

dalvyx [7]

Given that,

The speed of a wave, v = 200 m/s

Wavelength, $\lambda=2\ m$

We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :

$v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz$

So, the frequency of this wave is 100 Hz.
